About The Geomorphology and Sediment Transport Laboratory

The Geomorphology and Sediment Transport Laboratory (GSTL) is a U.S. Geological Survey (USGS) facility located in Golden, Colorado on the eastern side of North Table Mountain. The USGS has a long and distinguished record of scientific research on flow and sediment transport in rivers; this lab represents a continued commitment to basic and applied research in this important area.

Work at GSTL falls into three primary categories:

  • basic research on fluid and sediment-transport mechanics governing the morphodynamics of rivers
  • applied research dealing with specific issues in rivers
  • software development, verification and dissemination for models of physical processes in rivers

Our capabilities include:
